1st of all, I know very little about electricity except it can “bite” and higher voltages and amperes.
My brake controller is not working as it should. It worked well on a trip in March, and not so well on a recent trip. It is a Valley Odyssey (proportional controller). The trailer brakes seem to work fine when I pull the emergency braking cable…..I can barely move the trailer with that engaged. With the brake controller engaged at the highest setting, I can move the trailer fairly easy. I the brakes are adjusted correctly.
I measured the voltage at the Bargman Plug, and relayed the information to a Valley tech. He said I need to measure the amperage, not the voltage. I have a multi-meter that has 300m, 30m, 3m, and 60y on the dial. I figured those were mille-amps, and would not measure what I need.
His concern was that I might have a amperage drop in my truck wiring. I do have a voltage drop of .9 volts, comparing the voltage on my Scan Gauge (11.9 volts) and the multi-meter measurement at the Bargman (11.0 volts). Who knows how accurate the Scan Gauge measurement is.
With this voltage drop, would the amps also drop off significantly ??
What type of meter and how would I measure the amps ??
Quite frankly, I am about ready to buy a P2 or P3 and forget about the Valley unit, but I don’t want to spend the bucks if the Valley is still good and my truck wiring has a problem.
Thanks in Advance, Chap
